Definitions
- the invention relates to domestic mixers intended especially for crushing food materials immersed in a liquid.
- a known domestic mixer comprises a motor unit arranged to be held by hand and having in its lower part a rotatable driver for rotation at high speed.
- a mixing foot is mounted on the said lower part of the motor unit and encloses a vertical shaft, the upper end of the shaft being coupled to the said driver.
- the lower end of the shaft carries a mixing screw located under a cover provided at the lower end of the foot.
- Such known mixers are mainly used for preparing vegetable soups.
- the soup is homogenised by operating the mixer directly for a few moments in the cooking vessel. During this operation particles of vegetables immersed in the water are brought in contact with the mixing screw and are thus crushed.
- a domestic mixer for use in a liquid, comprising a motor unit arranged to be held by hand, a rotatable driver fixed in the motor unit, a mixing foot extending from the motor unit, and a shaft extending within said mixing foot, one end of said shaft being coupled to the said driver, a mixing screw coupled to the other end of said shaft, and a protective cover at the free end of the foot, wherein said mixing screw is movable between a safety position, in which it is located within the cover and a mixing position in which it projects beyond the cover, elastic restoring means urging said mixing screw into its safety position, said mixing screw being arranged to move against the action of the said restoring means to its mixing position when it rotates in a liquid, this displacement resulting from the screwing effect of the mixing screw in the said liquid.
- the lateral wall of the cover does not constitute an obstacle to the free circulation of the particles to be crushed, since the screw then projects beyond the cover.
- the screw is protected by the lateral wall of the cover surrounding it.
- FIG. 1 shows, partially in elevation and partially in cross-section, a mixer of the invention having a screw which is shown in the safety position;
- FIG. 2 is a view similar to FIG. 1 but showing the screw in the mixing position.
- the mixer illustrated comprises a motor unit 10 designed to be held in the hand and having in its lower part a rotary driver 12 for rotation at high speed.
- a mixing foot 14 is removably mounted on the lower part of the motor unit 10 and encloses a vertical shaft 16, the upper end 18 of which is coupled to the driver 12.
- the lower end 20 of the shaft 16 carries a mixing screw 22 which is fixed to the shaft and which is located under a protective cover 24 provided at the lower end of the foot 14.
- the protective cover 24 has a lateral wall 26 and a series of recesses 28 in the form of notches are cut out of the lower edge of this wall 26 and distributed over the periphery thereof.
- This lateral wall carries on its edge at least two downwardly directed extensions 30 which are spaced peripherally from one another. It will be seen that the peripheral space between these extensions 30 is considerably greater than the peripheral width of each of the notches 28.
- the shaft 16 is rotatably coupled to the driver 12 by means of a sleeve joint which allows axial play of the shaft 16 relative to the driver 12.
- This sleeve joint is provided by two diametrically opposite axial grooves 32 in the driver 12 and two lugs 34 on the shaft 16 which are arranged to engage freely in the grooves 32.
- the assembly formed by the shaft 16 and the screw 22 is mounted in the foot 14 and is movable between an upper, safety position shown in FIG. 1 and a lower, mixing position shown in FIG. 2.
- the screw 22 In the upper, safety position, the screw 22 is located in the space within the cover 24, and the assembly is stressed towards this safety position by elastic restoring means 36 within the foot 14.
- the screw 22 In the lower, mixing position the screw 22 has been moved downwardly out of the cover 24.
- the assembly of the shaft 16 and the screw 22 moves automatically into the mixing position against the action of the restoring means 36 when the screw 22 rotates in a liquid, this displacement resulting from the effect of the screwing of the screw in the liquid.
- the restoring means 36 consists of a helical spring coaxial to the shaft 16 and located between a fixed seat 38 made in the foot 14 and a movable seat 40 carried on the shaft 16.
- a sleeve 42 is located between the spring 36 and the shaft 16, the lower end of which, and in the lower position shown in FIG. 2, the sleeve 42 rests against the seat 38, with an anti-friction washer 44 interposed, such that the seat 38 and sleeve 42 define the lower limit of the axial displacement of the shaft 16.
- extensions 30 of the lateral wall 26 of the cover extend downwardly beyond the screw 22 in the lower mixing position. These extensions provide supports designed to rest against the bottom of a vessel containing the liquid and ensure that the screw is suitably spaced from the bottom of the vessel during mixing.
- the screw 22 When the mixer is in the working state, that is to say introduced into the liquid, the screw 22 is located at a level lower than the teeth of the wall 26.
- the largest pieces of vegetables can pass freely between the extensions 30 so as to reach this screw.
- the smallest particles can pass either through the notches 28 or between the extensions 30.
